DROPI-STAND FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 541,474, dated June 25,1895.

r Application filed March 13,1895. Serial 110,541,546; (in) mini-e1.)

To all whom it may concern THOMAS KRAEMER, citizens of the UnitedStates, residing at'Elizabeth, in the county of '5 Union and State ofNew J ersey,have invented certain new and useful Improvements inDrop-Stands for Sewing-Machines, of which the following is aspecification,'reference be-' ing had therein tothqaccOmpanying-drawwings. I

structedthat the machines,' when not in use,

' may be dropped down beneath the surfaces.

of the tables and the openings in the tabletops be thencovered over byfoldingextemsion' leaves so thatthe tables may be-usedfor other purposesthan assewingmachine tables; and our invention has for its object toprovidea sewing machine drop-stand or table,"of the class referred to,which will be strong and durable, and thus little liable to get-out oforder, while at the same time it will be'neat and attractive inappearance and convenient in use, as well as simple in construction, sothat it may be manufactured at a minimum cost.

In carrying-our invention into efiect we provide a hinged support whichis arranged at the right hand end of the opening in the table-top inwhich the machine bed-plate is received, or at the end of said openingbeneath the fly and pulley wheel of the machine.

The said hinged supportis provided with openings for the passage of thedriving belt and has also a lip extending beneath the bed plate ofthemachine. Beneath the table, at the rear of the machine, is a torsionalcoil spring one end of which is held stationary while the other endthereof engages said hinged support so that said spring serves tocounterbalance the weight of the machine when the latter is turned downon its hinges beneath the table top.

In the accompanying drawings, Figure 1 is a'front view of asewing-machine stand embodying our invention. Fig. 2is a plan View ofthe same. Fig. 3 is a section through the table. Fig. 4 is a detail ofone of the hinges 5o connecting the machine bed-plate to the table.

Our invention relates to that class of sew-f ing machine stands ortables which are so con-.

Adenotes the table having an opening a which receives the bed-plate b ofthe machine said bed-plate being connected at its rear side 5 5 to saidtable by double acting hinges" b of such'construction as to permit themachine to be-dropped down below the table-top or tilted over backwardabove the table when access to the mechanism under the bed-plateisdesired. The bed-plate b isnormally supported at its front side by ahingedleaf A having a lip at extending beneath said bed-plate.- A is anextension leaf which, when the machine is dropped below the uppersurface of the table, is folded over, as denoted by dotted lines in Fig.1,1:0 cover the opening down through which they machine has passed, torender the table fit for use for other purposes than-as a sewing machinetable.

O is. a sustaining plate or support placed at the right hand end of theopening a and hinged at its rear end to a bracket 0 beneath the tabletop, said hinged support having near its front end a lip or lug 0'extending under the machine bed-plate b, and said support being providedwith belt openings '0 D is atorsional coil spring surrounding lateralextensions or bars 6 preferably cast integral with bracketsor hangers e,e secured to the under side of the table-A, the bracket or. hanger ebeing preferably cast integral with the bracket 0 to which the support 0is hinged. One end at of the spring D extends beneath the support 0 andis received in a groove 0 formed by ribs 0 and the other end d of saidspring engages a collarfon the extension e of the bracket e. The collarfis normally held stationary, as by a pin g en gaging a part of thebracket 2 and entering any one of the holes f in said collar. The stressof the spring D may be regulated, to secure the proper tension, byturning the col- 1ar-f in one direction or the other, asf'will bereadily understood.

H denotes a box or housing secured to the under side of the table A andserving to inclose the machine and protect the same from dust when it isdropped beneath the table. The lower wall of the housing may also serveroo o r the torsional springis conveyed to the hinged gaged directlywith the machine bed-plate.

as a drip pan, or may be metal line for this purpose; I- a Whenthemachine is to be dropped below the table its front side is first liftedslightly so that the hinged leaf A may be raised to bring its lip aout'ofrange of the front edge ofthe machine bed-plate-and the machinemay then be lowered into the receptacle beneath the table, and. in thisoperation the couuterbalancing spring D prevents'any accidental jar oi"strain on the hinges b which might otherwise result in thus lowering theIn fact it said stress is increased. In lifting the machine to workingposition the operation is assisted by the spring D as will beunderstood, so that butlittle force is required to be exerted by theoperator. 7 T 1 When, the machine is tilted over above the table foraccess to the works beneath the bed plate, the support 0 is preventedfrom being lifted above the table Aby the engagement of the rear end ofsaid support with the part The part 0, although herein termed a, support, does not sustain the machine whenthe latter is in workingposition, the machine, at such times, being supported by the hinges bandthe lip a of the hinged leaf A. The support 0, in its normal orraisedposition, is, preferably flush with the top of the table A and thuspractically forms an extension of the machine bed-plate b which is ofless length than the opening a, said support and bedplate together justfilling the said opening.

lVe do not wish to be understood as limiting our invention to all of thedetails herein shown, as these details may be varied considerablywithout departing from the spirit of our invention.- For example, themachine bed-plate hinged to the table at one side might be supported atits opposite side by sliding latches or other movable equivalents forthe hinged leaf A with its lip a. Also instead of employing the hingedsupport 0, through the medium of which the stress of bed-plate of themachine, said support might be dispensed with and the said spring en-Having thus described our inventiomfwe claim and desire to secure byLetters Pat-.
